Title: Method for preparing stratified metallic semi-finished products, particularly made from steel, and device for implementing this
Inventor: DUMONT-FILLON JACQUES
IPC: B23K5/10
Filed: 1984-02-22
Abstract: The invention relates to the preparation of stratified polymetallic semi-finished products which consists in continuously casting a bar serving as base metal A (generally a slab) and, during its extraction, the surface 3 to be covered is descaled at the exit from the unbending zone 2, then, optionally, this surface is scoured by spreading a powder 10 consisting of a slag, then additional (filler) metal is deposited in the form of a single strip or of a plurality of juxtaposed strips 14 with the aid of an array of uncoilers 13 and, at the same time, heat is supplied 16, localised at the point of the contact between the additional (filler) metal and the base metal, this supply of heat being produced so as to cause the momentary melting of the strip 14, either completely at the instant when it is deposited or just after, or at the surface only on its face intended to come into contact with the base metal, and finally in perfecting the surface appearance by performing a surface improvement operation by means of compression between two rolls 17.

Title: Image detection apparatus
Inventor: WILLIAM MORRIS
IPC: H01L27/148
Filed: 1984-04-16
Abstract: The invention relates to image detection techniques. A reliable and relatively economical means for obtaining a rapid response in an image detection apparatus with a charge-coupled semiconductor device consists in incorporating in the apparatus a radioactive light source in order to illuminate the charge-coupled material, to an extent sufficient to polarise it to a "bald zero" in the case of a charge-coupled device with a surface channel, or to a "light-faced zero" in the case of a charge-coupled device with a buried channel. Application to detection systems.

Title: Closure for sterilising container
Inventor: GARDES JEAN-CLAUDE
IPC: A47J27/08
Filed: 1984-07-27
Abstract: The container has a fitting lid (3) which is pulled onto a sealing gasket (4) by the rotating closures, mounted around the container.
